That is a 1964-65 HUFFARK....a mix between Huffy and Monark.
Huffman owned Monark at the time and they used the name to tweak their bicycles for small catalog order stores.
This bike was probably supposed to be an Eldorado, in optional gold (making this a 1965 model). Instead, someone grabbed a tank from the previous year / Monark line and put the Thunderbird graphics on it. The Thunderbird was a Monark model. The rack is also from the economy line, as the Eldorado rack had large chrome legs on the side.
Of course, that is the older style frame. The Eldorado used the new "Spaceweight" frame, with the chrome bullets in front. It is possible this is a 1964-65 Monark Thunderbird with Huffy decals on the guard and rack. In retrospect, I think THIS is the case.
Value? It's a handsome vintage bike that you won't find in anywhere else. I say about $150-$250 is fair. The headlight is in remarkable condition and that makes a huge difference!
